Abstract
An augmented reality system and method of operating the same is provided. An end user is allowed to visualize direct light from a three-dimensional scene in an ambient environment, generating virtual image data from the point of the view of the end user. A region of spatial overlap between a real object in the three-dimensional scene and a virtual object in the virtual image data is determined. Color characteristics of the real object in the overlap region are determined. A perceived contrast between the real object and the virtual object in the overlap region is decreased based on the determined color characteristics of the real object in the overlap region. The virtual image data is displayed as a virtual image after the perceived contrast between the real object and the virtual object has been decreased that, along with the visualized direct light, creates a three-dimensional augmented scene.
